A ripper shank holding assembly includes a first transverse bar fixedly attached to each of the plates, a detachable taper pin and detachable shear bolt. A ripper shank has a notch adapted to receive the transverse bar and the taper pin and shear bolt abut a rear surface of the ripper shank when the ripper shank is mounted between the two vertical plates. A finishing tool holding assembly includes a second transverse bar fixedly attached to each of the plates and a second detachable shear bolt. A finishing tool has a notch adapted to receive the second transverse bar with the second shear bolt extending through an aperture in the finishing tool when the finishing tool is mounted between the two vertical plates.
